Attwood 11200-1 Boat Trailer Rubber Bow Stop V-Block
The Attwood 11200-1 uses a deep 80° V design to cradle the boat bow securely. Made from natural black rubber, it resists wear during frequent loading cycles. Its 2″ x 2″ form with a 3″ opening makes it suitable for compact trailer setups and small to mid-sized bows. Best for light to moderate-weight bows on standard trailers; avoid for very large hulls on oversized rigs due to the small opening.
Attwood 11202-1 Boat Trailer Rubber Bow Stop V-Block
The 11202-1 is a larger, 4″x4″ black rubber block designed to protect the bow while keeping the boat centered on the trailer. This model helps prevent side-to-side movement and is well-suited for mid-to-large bows on bigger trailers. Choose this if your bow is prone to shifting at highway speeds, but note it may be bulkier for compact trailer beds.
SYOWADA V-Span Boat Trailer Bow Stop
The SYOWADA bow stop features a 2″ x 4″ block with a 1/2″ mounting hole and a polyurethane body. It provides anti-corrosion and scratch-resistant properties to protect the hull during loading and unloading. It reduces impact to prevent hull damage and helps keep the bow centered. Best for boats that require durable, non-marking stops; limit: polyurethane mounting may require exact alignment during installation.
UANOFCN 2″ V-Style Marine Bow Stop
The UANOFCN bow stop provides a 2″ V-style cradle with a 1/2″ mounting hole diameter. It focuses on full protection, shock absorption, and a secure hold for towing. Best for boats needing strong stabilization without marks on the hull; limitation: may be bulkier than ultra-compact options for very small trailers.
Sunicon V Boat Trailer Roller Stop
The Sunicon V-stop uses a 3″ width and 5.3″ span with a 1/2″ mounting hole. It employs upgraded polyurethane material to provide vibration absorption and a no-mark towing experience. Best for medium to larger bows, where hull protection and stable tracking are priorities. Consider fit on smaller trailers due to its wider base.
Buying Guide
What is a bow stop and why does it matter?
A bow stop secures the boat’s bow to the trailer, preventing movement during loading, transport, and unloading. It reduces hull contact with the trailer and minimizes sway that can cause scratches or hull damage.
Material and finish considerations
Common materials include rubber and polyurethane. Rubber offers flexibility and good grip but can wear over time. Polyurethane tends to be tougher, scratch-resistant, and non-marking, which is important for sensitive hull coatings.
Size and mounting compatibility
Bow stops come in various widths and mounting hole diameters. Match the stop width to your bow block width and ensure mounting holes align with trailer frame holes for secure attachment.
What to prioritize: protection, fit, or ease of installation?
Protection: choose a high-durability material that absorbs impact. Fit: ensure the bow stop accommodates your boat’s bow shape and trailer bed width. Installation: consider whether your trailer allows straightforward mounting with available hardware.
Which bow stop should you avoid for your trailer?
Avoid stops that are too narrow for your bow or too bulky for your trailer’s bed. Also, avoid materials that may scratch your hull if your boat has a sensitive finish.
Installation tips
- Align the bow stop with the trailer winch post to keep the boat centered.
- Check for proper mounting hole diameter and secure with corrosion-resistant hardware.
- Test in a controlled area before a long tow to verify the boat remains stationary.
Maintenance and longevity
Regularly inspect for cracks, wear, or deformation. Clean off road grime after use and apply appropriate protectants compatible with rubber or polyurethane materials.
FAQ
- What size bow stop should I choose for a small fishing boat?
- Will polyurethane stops scratch my boat?
- Are larger stops better for heavy boats?
- Can bow stops be reused after impact damage?
- Is rubber better than plastic for bow stops?
- Do I need professional installation?
Choose a compact option around 2″ x 2″ to 2″ width with an appropriate mounting hole if your trailer bed is narrow.
No, many polyurethane stops are designed to be non-marking and provide smooth contact with hull surfaces.
Yes, larger stops can distribute pressure more evenly and reduce bow movement for heavier hulls, but require compatible trailer space.
It depends on damage. Inspect for cracks or deformation; replace if the integrity is compromised to maintain safety.
Rubber offers flexible grip and cushioning; plastic (polyurethane variants) can provide greater durability and scratch resistance.
Professional installation isn’t required, but ensure proper alignment and secure mounting to avoid unsafe towing conditions.
